Cooling Suit

Abstract

The present invention aims at providing a cooling suit having a simple structure and capable of assuredly vaporizing a large amount of perspiration. To this end, there is provided a cooling suit to be worn on a wearer, comprising: an air inlet 2a configured to introduce outside air; parallel airstream generation means 3 for introducing the outside air through the air inlet to generate parallel airstreams which are substantially parallel to the wearer's body; a guide sheet simultaneously serving as a garment 2 and for guiding the parallel airstreams generated by the parallel airstream generation means, parallelly to the wearer's body; an air exit portion configured to discharge the parallel airstreams to the exterior; and electric-power source means for supplying electric power to the parallel airstream generation means; wherein the parallel airstream generation means cooperatively blows air of a total amount of about 5 m3 / H to 500 m3 / H into between the guide sheet and an undergarment or wearer's body to cause positive pressures between the guide sheet and the undergarment or wearer's body to thereby produce an air flow space therebetween, and the parallel airstream generation means causes the blown air to flow through the air flow space to thereby discharge moisture due to perspiration to the exterior and to thereby constantly feed fresh outside air into the air flow space, thereby largely intensifying conditions where perspiration can be evaporated.

Description

TECHNICAL FIELD [0001] The present invention relates to a cooling suit configured to cool a wearer's body by causing outside air to flow along the wearer's body parallelly thereto. BACKGROUND ART [0002] It is possible to regard a human as an extremely inefficient working device which ingests food to conduct life support activities, pieces of work, and the like, and to generate heat commensurately therewith. Due to the inefficiency, most of caloric intake is turned into heat, thereby requiring radiation of a large amount of heat commensurating with a then quantity of work in order to keep a normal body temperature. To this end, humans each possesses a physiological ability for cooling his / her body by virtue of perspiration. Namely, there is determined a physiologically required quantity of heat radiation commensurately with a quantity of work, and perspiration is exuded commensurately therewith, in a manner to attain heat radiation which is most suitable for the then situation of him...

AI Technical Summary

Benefits of technology

[0010] The cooling suit according to the present invention is capable of causing a large amount of air to flow between an undergarment or wearer's body and a guide sheet so as to largely extend an effective area under the influence of a physiological cooling ability of the wearer to thereby cool the wearer's body.BRIEF DESCRIPTION OF THE ACCOMPANYING DRAWINGS

Problems solved by technology

It is possible to regard a human as an extremely inefficient working device which ingests food to conduct life support activities, pieces of work, and the like, and to generate heat commensurately therewith.

Due to the inefficiency, most of caloric intake is turned into heat, thereby requiring radiation of a large amount of heat commensurating with a then quantity of work in order to keep a normal body temperature.

However, it becomes impossible to obtain a required quantity of heat radiation when vaporization of perspiration is disabled depending on conditions of temperature, humidity, presence / absence of airstreams, quantity of work, and the like, such that perspiration is continuously and uselessly exuded in a liquid state without vaporization, thereby causing not only uncomfortableness but also physiological damages.
